The warpage in injection-molded thin-walled components is a research challenge for many years. Polyoxymethylene (POM) composite was prepared with various weight fractions of talc to investigate the reduction in warpage and its effect on mechanical properties such as tensile, compressive, impact, and thermal properties like Vicat softening point and heat deflection temperature (HDT). The uniform distribution of talc fillers is confirmed in Fourier transform infrared (FTIR) examinations. The talc is found to act as a nucleation

During the last few decades, considerable developments have been achieved in the area of computer-aided polymer processing. Injection molding is one among the most important processes which is benefited from the computer aided engineering. Even though injection molding is simple in principle the real process is quite complex. Simulation and optimization algorithms can be development tools that make the difference between success and failure. The processors are more interested in manufacturing good quality products with lower cycle time. It is difficult to compensate both two factors since the complexibility of multiple process parameters. Location of gates in the mould plays a vital role in processing of injection moulding machine. With different gate location the quality criteria may change and also the aesthetic appearance of the product affected. In our research the closely same designed gates are designed for given part and optimized mould design before mould making. The gate location optimization is done by the simulation software itself to focus on lower quality prediction. we have modeled a simple injection molded component in Proengineer. The same model is analyzed for two different gate location as centre gate and edge gate using plastic advisor, simulation software from Proengineer. The process ability of each gate is analyzed against the process variables like fill time, injection pressure profile, and cooling quality, for optimized quality predictions and optimized cycle time.
